I just bought this 2018 bike new in November, had 3 miles on it. The tires are Schwalbe Magic Mary, 27.5 and 2.8 wide. I noticed last night on our ride at Mueller Park that the tread is starting to fall off of one side.
Although I just bought it 6 months ago, I have logged 300 miles, so maybe this is expected? But yikes, a couple hundred dollars per year on tires does not sound fun.
